This patch series combines the work Michael Roth has done in supporting SEV guests in selftests and the work Sean Christopherson suggested to allow ucalls from SEV guests. And the work Sean has sent to consolidate the ucall boilerplate code. Along with a very simple version of the SEV selftests Michael originally proposed. V3 * Addressed more of andrew.jones@ in ucall patches. * Fix build in non-x86 archs. V2 * Dropped RFC tag * Correctly separated Sean's ucall patches into 2 as originally intended. * Addressed andrew.jones@ in ucall patches. * Fixed ucall pool usage to work for other archs V1 * https://lore.kernel.org/all/20220715192956.1873315-1-pgonda@xxxxxxxxxx/ Michael Roth (6): KVM: selftests: move vm_phy_pages_alloc() earlier in file KVM: selftests: sparsebit: add const where appropriate KVM: selftests: add hooks for managing encrypted guest memory KVM: selftests: handle encryption bits in page tables KVM: selftests: add support for encrypted vm_vaddr_* allocations KVM: selftests: add library for creating/interacting with SEV guests Peter Gonda (3): tools: Add atomic_test_and_set_bit() KVM: selftests: Add ucall pool based implementation KVM: selftests: Add simple sev vm testing Sean Christopherson (2): KVM: selftests: Consolidate common code for popuplating KVM: selftests: Consolidate boilerplate code in get_ucall() tools/arch/x86/include/asm/atomic.h | 7 + tools/include/asm-generic/atomic-gcc.h | 15 + tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 3 + .../selftests/kvm/include/kvm_util_base.h | 25 ++ .../testing/selftests/kvm/include/sparsebit.h | 36 +-- .../selftests/kvm/include/ucall_common.h | 14 +- .../selftests/kvm/include/x86_64/sev.h | 47 +++ .../testing/selftests/kvm/lib/aarch64/ucall.c | 38 +-- tools/testing/selftests/kvm/lib/kvm_util.c | 267 +++++++++++++----- tools/testing/selftests/kvm/lib/riscv/ucall.c | 43 +-- tools/testing/selftests/kvm/lib/s390x/ucall.c | 40 +-- tools/testing/selftests/kvm/lib/sparsebit.c | 48 ++-- .../testing/selftests/kvm/lib/ucall_common.c | 139 +++++++++ .../selftests/kvm/lib/x86_64/processor.c | 15 +- tools/testing/selftests/kvm/lib/x86_64/sev.c | 249 ++++++++++++++++ .../testing/selftests/kvm/lib/x86_64/ucall.c | 39 +-- .../selftests/kvm/x86_64/sev_all_boot_test.c | 131 +++++++++ 18 files changed, 911 insertions(+), 246 deletions(-) create mode 100644 tools/testing/selftests/kvm/include/x86_64/sev.h create mode 100644 tools/testing/selftests/kvm/lib/ucall_common.c create mode 100644 tools/testing/selftests/kvm/lib/x86_64/sev.c create mode 100644 tools/testing/selftests/kvm/x86_64/sev_all_boot_test.c -- 2.37.1.559.g78731f0fdb-goog
